Locking when inside

[Precambrian]

I'm starting to convert a 2022 Sprinter but am wondering what others do about locking the van when inside. I'm planning on a new partition so the cab area isn't accessible.

The rear has a motion sensor which is easy enough to cover up to stop the alarm going off, but the fob only has 2 buttons for global lock/unlock. Is there a way to manually lock just the front doors? Do people lock the whole van using the fob and then open the sliding door from the inside?

This is probably a really daft question I know. I just hadn't considered what to do about this simple thing in daily use.

Use the lock on the dash board as it won't set the motion sensor, it will just set the doors
